ALLOCATION OF A SERVING ENTITY IN A COMMUNICATION NETWORK

摘要

The invention relates to a control entity (I-CSCF 5), serving entity (S-CSCF 1; S-CSCF 2) and a subscription entity (HSS 6), in which a control entity determines that the most preferred serving entity (S-CSCF 1) was not selected for a user and transmits an indication about selection of less preferred serving entity to the less preferred serving entity (S-CSCF 2) which in turn transmits corresponding in indication to a subscription entity. The subscription entity stores the indication and returns the server capabilities to the control entity when information about the same user is requested next time.
